Description
Technical field
The utility model relates to a kind of thermostatic type air curtain type energy-saving ventilating air cabinet.
Background technology
The discharging of existing laboratory toxic gas generally adopts plain edition vent cabinet or atom to absorb cover.They exist, and control range is little, energy consumption is high, cause that easily poison gas escapes and unsafe situation.Especially atm number, high flow rate the time, the processing controls difficulty is bigger.The structure of plain edition vent cabinet is that cabinet adds an exhaust equipment, it is to produce by traditional controlled wind speed law theory design, the decay of inspiratory flow rate is very fast, want to guarantee that the whole operation mouth has certain controlled wind speed, avoiding in the cabinet harmful substance to escape need very big power consumption, and simultaneously, the effect of this product when not having operating personnel to operate is all right, personnel's interference in air flow when working face is walked up and down is very big, and the very easy interior gas of cabinet that causes escapes.Particularly build for modern experiment, under the condition that is equipped with central air-conditioning, central heating and ventilation system, the said goods is drained indoor air, can cause very big energy loss, causes summer and causes thermal loss in loss of refrigeration capacity, the winter of air-conditioning.Atom absorbs cover because it is small-sized local exhaust device, and size is little, and control range is little, and it is bigger to fluctuate.
The content of invention
The purpose of this utility model is that existing laboratory hood control range is little, energy consumption is high, cause that easily poison gas escapes and unsafe shortcoming in order to overcome, a kind of thermostatic type air curtain type energy-saving ventilating air cabinet is provided, and the discharging of its toxic gas is more effective, safe and energy-conservation.
The purpose of this utility model is achieved in that it comprises the deflector in main cabinet, the main cabinet, the exhaust hood and the illuminating lamp source on main cabinet top, it is characterized in that main cabinet the place ahead connects a relatively independent air curtain generation cabinet, air curtain takes place cashier's office in a shop, and portion installs and fixes the inlet box (mouth) of being with the primarily efficient filter device, the middle part is with the screw mounting heat exchanger that tilts, air intake surface up, centrifugal blower is fixed on the air curtain generation cabinet inwall, outlet is over against the air intake surface of heat exchanger, and clamp into bar seam wind pushing nozzle air curtain generation cabinet bottom; The main cabinet bottom, below of bar seam wind pushing nozzle is equipped with a Under The Grille suction inlet.
Adopt simple mechanical connection between described each parts, i.e. screw or screw rod connection, welding, cramp joint, snapping or articulate.
Described air curtain generation cabinet material is selected from corrosion resistant plate, steel plate, timber or plastics, selects for use according to customer requirements.
The filler of described primarily efficient filter device is selected from non-polypropylene fiber, terylene non-woven fabric or the activated carbon activation glass knitted.
The preferred multimedium heat exchanger of described heat exchanger: adopt inwall successively to carry out frosted and handle the thickening seamless copper pipe and the ripple aluminum heat exchanger fin that increase inwall heat exchange area and oxidation processes and increase antiseptic property, external diameter 8MM, internal diameter 5MM and be welded; Or adopt stainless steel tube and ripple aluminum heat exchanger fin to be welded.
The inlet box (mouth) of described band primarily efficient filter device, heat exchanger, centrifugal blower, bar stitch wind pushing nozzle and can add the sealing of fluid sealant or sealing ring being connected of air curtain generation cabinet.
The course of work: main cabinet is the experimental implementation district, is the zone that dusty gas produces.Open earlier the valve of heat exchanger tube in the heat exchanger before the operation on demand, connect cold water, hot water, condensate liquid, the discarded liquid of middle temperature or waste gas.The air that enters from inlet box (mouth) through the primarily efficient filter device filter and centrifugal blower after, in the heat exchange effect of heat exchanger by cold (heat) medium, outdoor air is adjusted to indoor identical temperature, form air curtain through bar seam wind pushing nozzle, in the inside and outside formation of main cabinet isolation strip, guarantee that gas does not escape in the cabinet.Simultaneously, under the effect of exhaust blower, cabinet forms negative pressure outside; regulate the air quantity of outer exhaust blower this moment, the pressure reduction of switch board inside and outside can be sucked away the air curtain gas that arrives the Under The Grille suction inlet fully; protect the gas of indoor environment not drained or drain on a small quantity fully, and operate unaffected.
Advantage of the present utility model and good effect: utilize the blowing and drawing type type of flow of jet theory development, the energy density height of jet, velocity attenuation is slow, cooperates the multimedium heat exchanger, and constant temperature air-supply theory reaches several respects synergy:
(1) do not destroy indoor flowing gas state, and can control the discharging of the dusty gas of cabinet inner working face fully, can not drain the cooling and heating load in air-conditioning (heating) room, energy-saving effect is remarkable;
(2) multimedium design of heat exchanger cooperates the Building Cooling source to be provided with, and initial cost is little; Also can cooperate waste heat recovery by various condensate liquids, the discarded liquid of middle temperature, energy-conservation more obvious;
(3) leaving air temp of wind pushing nozzle can match with the temperature in room, and supply air temperature difference is few, reduces the discomfort that blowing feeling brings;
(4) type of flow of blowing and drawing type compares K by constant flow
eAdjusting is sent, the air draft air quantity, and operating surface speed is not subjected to the restriction of sliding door aperture, guarantees the working face constant speed;
This synergistic result makes laboratory hood more effective, safe and energy-conservation to the discharging of toxic gas.
The drawing explanation
Fig. 1 is the utility model structure (analyse and observe the side) schematic diagram.
Concrete embodiment
Below in conjunction with Fig. 1 the utility model is further described, but does not constitute restriction of the present utility model.
Thermostatic type air curtain type energy-saving ventilating air cabinet as shown in Figure 1, it comprises the deflector 2 in main cabinet 9, the main cabinet 9, the exhaust hood 1 and the illuminating lamp source 3 on main cabinet 9 tops, it is characterized in that main cabinet the place ahead connects a relatively independent air curtain generation cabinet 10, air curtain generation cabinet 10 tops install and fix the inlet box 4 of band primarily efficient filter device, the middle part is with screw inclination mounting heat exchanger 6, air intake surface up, centrifugal blower 5 is fixed on air curtain generation cabinet 10 inwalls, outlet is over against the air intake surface of heat exchanger 6, and clamp into bar seam wind pushing nozzle 7 air curtain generation cabinet 10 bottoms; Below main cabinet 9 bottoms of bar seam wind pushing nozzle 7 are equipped with a Under The Grille suction inlet 8, adopt simple mechanical connection between each parts.
Air curtain generation cabinet material is a steel plate, once is pressed into by the steel plate mould.The filler of primarily efficient filter device is an activated carbon activation glass.The preferred multimedium heat exchanger of heat exchanger: adopt inwall successively to carry out frosted and handle the thickening seamless copper pipe and the ripple aluminum heat exchanger fin that increase inwall heat exchange area and oxidation processes and increase antiseptic property, external diameter 8MM, internal diameter 5MM and be welded.Heat exchanger 6, bar seam wind pushing nozzle 7 add the fluid sealant sealing when being installed to air curtain generation cabinet 10.The inlet box (mouth) 4 of band primarily efficient filter device directly is buckled in air curtain generation cabinet 10 tops and tightens up with self-tapping screw and gets final product, and is convenient for changing and keeps in repair miscellaneous part.It is centrifugal blower that centrifugal blower adopts low noise DKT.
